Or you can just use quassel, which has clients for android, iOS, windows, Mac Linux and the web, works exactly like IRCCloud, is fully open source, and is able to run on a 2$/month webserver.
That cloud server does other stuff, but the cost isn't really a factor for me. IRCCloud doesn't let me connect with an IRC client. I can only use the mobile apps or my browser. Many don't mind that limitation, but it's a deal-breaker for me.
